VALVE.

Patented Aug. 1, 1905.

To all whom, it may concern:

Be it known that I, OTTo H. MUELLER, a subject of the German Emperor, residing at Berlin, Kingdom of Prussia, Germany, have linvented certain new and useful Improvements in Valves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to an improved valve for pumps or compressors, the special object of the invention being to provide a simple, cheap, and eiiicient spring-pressed valve construction, providing for a large valve-opening and efficient guiding of the valve and avoiding the escape of the spring in case of break.

In the accompanying drawings I have shown a construction embodying all the features of the invention as applied in their preferred form and a modification thereof, and

'this valve construction will now be described in detail and the features forming the invention particularly pointed out in the claims.

In the drawings, Figure 1 is a central section of the valve on the valve-seat with the valve closed. Fig. 2 is a plan view ofthe valve of Fig. 1. Fig. 3 is a detail section of the valve proper and guide-sleeve of Fig. 1. Fig. l is a View similar to Fig. 1, showing a modification.

Referring to said drawings, A is the valveseat, provided with the circular or ring port a. B is the ring-valve closing said port and which is .formed with the extended sleeve O, by which the valve is guided and the valvespring inclosed.

Within the sleeve C and the ring-valve B is the valve holder and guide D, which is starshaped, having in the form shown four wings 10, and this holder is adjustably secured in the valve-seat A by screw-head 11, formed lwith or secured to the wingsand screwed into thevalve-seat. The wings 10 have wider portions or heads at their outer ends, so as to eX- tend to the full inner diameter of the sleeves C, these heads forming an efficient guide for the outer end of the sleeve C as the valve opens and closes, and the wings inside the heads are of such reduced width as to provide space between them and the sleeve O for theY coiled, valve-spring E, which encircles this portion of the wings. The heads at the outer ends of the wings 10 also provide shoulders 1, against which the outer end of the spring E abuts, and the inner end of the spring E `rings.

sleeve C protects the sprmg against injury abuts against shoulders 2, which are formed a-t the inner end of the sleeve Cthe spring thus being under tension between the shoulders 1 and 2 of the valve-holder D and the sleeve C. This shoulder 2 is formed by an inwardly-projecting portion or ring 12, which forms a lower guiding-surface for the valve, by which the valve is vguided on the narrower portions of `the Wings 10. This guiding of the valve by the ring 12 on the narrower portions of the wings 10 and by sleeve O on the outer ends or heads' of the wings 10 secures a very eiiicient guiding of the valve B, so that it is capable of satisfactory use in either a vertical or horizontal position.

The spring E is put under tension by screwing the holder D into the valve-seat, and this tension may be increased or diminished by cutting away the shoulder 1 or putting in The inclosure of the spring E by the and in case of breakage of the spring holds it in place. By unscrewing and removing the holder D all parts of the valve are free from the valve-seat and readily disassembled.

An` important feature of my improved valves in the preferred forms shown is that the valve may readily be made complete with the sleeve O by pressing from sheet metal, so that4 the whole valve and guide-sleeve may be in-i tegral-and very cheaply made, and the valve may be of very light metal, as the efficient and positive guiding of the valve by the long sleeve O acting against the outer ends of the wings 10 and the ring 12 on the inner ends of the wings prevents any sidewise strain on the valve. The double discharge of these preferred forms-outward under the outer edge and inward under the inner edge and through the sleeve C between wings lO--also aids in securinga light valve, as it enables a large discharge to be secured with a small and narrow valve, so that the required strength may be secured with very light metal. This double discharge, however, is old and not essential tomy invention.

In the con/struction shown in Figs. 1 to 3 the ring 12 and spring-abutment 2 are secured by bending the metal inward from the sleeve O, the valve-disk extending outward from the ring. As shown in these figures also, the valve proper, B, is provided with an outward bend 13, forming a corrugation or rib over the port a, which strengthens the valve.

In the form shown in Fig. 4: the metal iS bent outward from thelower end of the sleeve C and then inward to form the valve proper, B, and the inner edge of the valve B is bent upward and over to form the ring 12 and spring shoulder or abutment 2, performing the same functions as in the construction shown in Figs. 1 to 3.

It will be understood that the invention is not limited to the exact form or construction of any of the parts shown, but that many modifications may be made therein, while retaining the invention defined by the claims.

What I claim is- 1. A ring-valve provided with an outwardlyextending guide-sleeve, in combination with a valve-spring inclosed within the guide-sleeve,

and a Valve-holder within said spring formingan abutment for the outer end of the spring and provided with guide-surfaces coacting with the outer and inner ends of the sleeve.

2. A valve device consisting of the ringvalve B and guide-sleeve C formed integral and having guide-ring 12 and spring-abutment 2, a valve-holder having a wider portion at its outer end forming spring-abutment 1 and a guide for the outer end of the sleeve, and a narrower portion forming a guide for ring 12,.and spring E within the sleeve C between the abutments 1 and 2 and inclosing the narrower portion of the holder.

3. A valve device consisting of the ring valve B and guide-sleeve C formed integral and having guide-ring 12 and spring-abutment 2, valve-holder D having wings 10 permitting discharge through the holder and having wider portions at their outer ends forming spring-abutments 1 and guides for the outer end of the sleeve, and narrower portions forming guides for ring 12, and spring E within the sleeve C between the abutments 1 and 2 and inclosing the narrower portion of the wings 10.

4. Valve B and sleeve C formed integral with guide-ring 12 and spring-abutment 2 cxtending inwardly from the sleeve.

5. Valve B and sleeve C formed integral from sheet metal with an inward bend at the valve end of the sleeve forming guide-ring 12 and shoulder 2 and the valve B extending outward from the ring.

6. Valve B and sleeve C formed integral from sheet metal with an inward bend at the valve end of the sleeve forming guide-ring 12 and shoulder 2 and the valve B extending outward from the ring and having rib 13.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
